I just recently bought my 1991 coupe and cant determine if synthetic oil has been used before. With 39000 miles on it is there any problem in using Mobil 1 5W-30 from now on. Opinions, etc??

After three months I drain it out of the vette and put it into my daily driver. I've been doing it for years with no ill effects. I'd rather have 3 month old Mobil in my VW than the 99cent/litre crap.
